Love the idea of a salsa-themed party. Since salsa is Caribbean (Cuba and Puerto Rico especially) I would go for drinks with rum, either light or dark. Mojitos are a great start. You may want to call them Salsitos and maybe add some raspberries to make the color red. Also, you may want to make Salsatinis, which can be based on the concept of a Martini drink but you can use Rum as the main ingredient. You can add any fruit flavored liqor and fruit juices and shake and strain in a martini glass. Garnish with fresh fruit.
An ice blended drink can be named Salsera, for example, and can be similar to a frozen Daquiry with any fruit flavor (passion fruit, pineapple, etc)._________________v.
